Introduction: How to Repair Your Damaged Headphones
Are your headphones or earplugs giving you problems. Don't throw them out yet. You can repair them yourself with this instructable. There are only three main problems which occur with headphones. They are
Damaged 3.5mm pin
If your headphones are damaged in any way you don't need to worry. Jumper1111 is here. All you need to do is replace the pin. First you will need to buy a new 3.5mm pin. Then cut out the old 3.5mm pin. There should be a total of 4 wires inside. There should be 2 wires of the same color they are both negative. The other two wires are positive for left and right speakers. If there aren't any wires but kind of threads you don't need to worry. They are wires also but enamel is covering them. If you want to expose the wire just burn those thread like wires a little and then rub them lightly with sandpaper. Well this should expose the copper of the wire.
Open the 3.5mm pin and connect one wire at each pin inside the 3.5 mm pin. They should be coming out from the back.
Now you will need to connect the wire of your headphone to this 3.5mm pin.
Connect the negative wires of the headphone to the wire which is attached to the longest pin in the 3.5mm pin.
Connect the other two wires to the remaining wires of the 3.5mm pin. Remember if both the positive wires touch each other it will give mono output.
If fixing the 3.5mm pin doesn't work then your problem might be in the wires. If you want to check if there's a problem in the wire or not you just need to connect your headphones to your ipod or anything. Then pull the wire a little and then slide your finger as shown in the picture. If you hear anything, even a little noise or feedback that means that there is problem in that part of wire. Just remove that part of wire and then connect the wire without that part and it should be fine. If you still hear nothing or bad sound then check if there are other parts of wire that are damaged.
If your headphones are still not working then that means you speaker is damaged. That means you will have replace your speaker. If your earplugs are damaged then I don't think that speakers of that size are available but if you have headphones then you can buy speakers of that size. WARNING- Your headphones could get permenantly damaged in this procedure. Do it at your own risk. Now all you need to do is go out and buy a 0.5 watt speaker. It should be 4 to 8 ohms. Now safely open your headphones and remove the damaged speaker and replace it with the new speaker. That's it just sooooo simple. If your headphones still don't work then I don't know what's the problem. You should ask someone who is older than me and has more experience(I'm 13). A video tutorial will be available soon enough.
